When you place a <label> inside the template of a panelbar, and click on that label, the select event fires twice instead of the expected once.
Note: works as expected on collapsible items, only items without children exhibit the problem.
Reproduction of the problem
the event keeps firing only once as if you clicked on any place in the item outside of the label.
